CARL E. FLATTER AND ORA E. CHRISTOPHER, OF ANDERSON, INDIANA, ASSIGNORS F ONE-THIRD TO LUTHER FLATTER, OF MUNCIE, INDIANA.

MIXING DEVICE.

Application filed May 29,

T 0 all whom it may concern:

Be it known that we, CARL E. F'LATTER and ORA E. CHRISTOPHER, citizens of the United States, residing at Anderson, in the county of Madison and State of Indiana,

have invented certain new and useful Improvements in Mixing Devices, of which the following is a specification.

This invention relates to a device for use with internal combustion engines which is adapted to thoroughly mix the gasoline vapor and air forming the explosive charge, it being amon the objects of this invention to produce a cevice which is simple in construction, compact, efficient, and which can be readily installed on an engine.

In carryin the objects of our invention into eifect, we provide a device which comprises a fan structure which is inserted between the carbureter and intake manifold of an engine, usually at the junction of the carbureter flange with that of the manifold. The device includes a relatively thin washer member which is held between the flanges and upon which the fan structure is mounted. Our mixing device is simple having but few parts, can be produced cheaply, and can be installed in various motor cars, airplanes, tractors, engines, etc., with no change in structure.

Referring to the accompanying drawings forming a part hereof, and in which similar reference characters denote similar parts,

Figure 1, illustrates an elevation of a carbureter and intake manifold with our device in place,

Figure 2, an enlarged View of our device,

and

Figure 3, a section on the line 33 of Figure 2.

The ordinary carbureter 1 has a flange2 which is secured to the flange 3 of intake manifold 4 by bolts, as is well known. The mixing device 6 is insert-ed between the flanges 2 and 3.

The mixing device comprises a relatively thin washer member 7 which can be inserted. between the flanges 2 and 3 without taking up a material amount of space and is thereby adapted to be installed without the change of any parts or the addition of any bulky members. The washer member 7 is secured between the flanges by the bolts 5 1920. Serial No. 385,270.

which pass through bolt holes 8 and 9 thereon. A spider 10 is formed centrally of the Washer member and a spindle 11 is secured to the center of the spider by upsetting one end to form a head 12. Near the opposite end of the spindle is an enlarged portion 13 for the reception of the fan structure, and a head 14 formed on the end adjacent to 13 provides means for preventing the fan from slipping off the spindle.

The fan consists of a pair of rings 15 and 16 havin a diameter such that they can be readily s lipped over enlargement 13, and clamped therebetween by means of pins 18 is a fan preferably formed from a single sheet of material struck up to form blades 17. A bushing 19 fits between the spider 10 and enlargement 13 serving to hold spindle 11 I and blades 17 in their proper positions. Various parts, such as the head 14, enlargement .13, and rings 15 and 16 are hardened to eliminate wear due to friction.

Having thus fully described our said invention, what we claim as new and desire to secure by Letters Patent, is:

A mixing device for internal combustion engines comprising a relatively thin washer member, a. spider formed centrally thereof, a spindle extending axially through said spider and having its end upset for securing it to the spider, an enlarged head formed at the opposite end of said spindle, an integral enlarged portion on said spindle of greater diameter than the spindle and of less dlameter than the enlarged head, a fan mounted on said enlarged portion of the spindle, a. ring on either side of said fan, pins extending transversely through said rings and the interposed portion of said fan, and a bushing surrounding said spindle and extending from said spider to said fan for holdmg the fan on the enlarged portion of said spindle and adjacent said enlarged head.

In witness whereof, we have hereunto set our hands and seals at Indianapolis, Indiana, this 26th day of May, A. D. nineteen hundred and twenty.
